HEATING AND VENTILATION
1
DESCRIPTION AND OPERATION HEATING AND VENTILATION UNIT
The heating and ventilation and blower units are
standard on all models. Air conditioning system is an
optional module, which when fitted provides fully
integrated climate control for the vehicle interior.
The heating and ventilation unit controls the air
distribution and heating to the vehicle interior. The
blower unit controls the volume of air supplied, while
the air conditioning module (when fitted) provides
refrigerated and dehumidified air.

80HEATING AND VENTILATION

DESCRIPTION AND OPERATION Through-flow ventilation
Through-flow ventilation is achieved by means of
one-way air extraction vents incorporated in both rear
quarter body panels. The vents open and close
automatically dependent upon the heating and
ventilation unit control settings and the volume of air
entering the vehicle.Heating and ventilation unit, controls
The Heating and Ventilation Unit is centrally located
and concealed by the dash assembly. When air
conditioning is fitted, an evaporator is mounted in the
heater unit forward of the heater matrix.
The dash mounted central controls are used to
operate both systems. A single switch controls the air
conditioning unit when fitted.

HEATING AND VENTILATION

DESCRIPTION AND OPERATION
Controls set for unheated air to footwells and face level vents
Heater and ventilation operation
The heating and ventilation system contains a heater
matrix, which is connected to the engine cooling
system, and a 4 speed fan for air distribution. Engine
coolant is circulated through the heater matrix
continuously, except when the temperature controls
are set to COLD.
Recirculated air
When the recirculation switch is pressed, an electrical
servo operates and fully closes the fresh air intake
flap.
Fresh air
When the recirculation switch is returned to the OFF
position, the electrical servo returns and fully opens
the fresh air intake flap.Heated air
Temperature output is controlled by the temperature
controls which move the air direction and temperature
flaps independently to increase or decrease the
volume of air flow through the heater matrix.
V8 Engine:When both controls are in the cold
position, the coolant valve is turned off.
Face level vent flap
Control at face level, flap fully open. All other vents
closed.
Control at face and foot level, flaps half open.
Unless an air conditioning unit is fitted, only fresh or
re-circulated air is available from the face level vents.
Demist vent flap
Control at demist, flap fully open. All other vents
closed.
Control at demist and foot level, flaps half open.

80HEATING AND VENTILATION
4
DESCRIPTION AND OPERATION Air direction flap
Flap moves across mixing chamber to direct the air
flow away from the heater matrix.
Air temperature flap
Control at HOT, flaps fully closed. All air flow passes
through heater matrix. As control is moved towards
COLD the flaps progressively open directing air flow
away from the heater matrix.
Control at COLD, flaps fully open.
V8 Engine:When both controls are at COLD, 2
micro-switches are closed and operate a vacuum
valve which closes the coolant valve.Air conditioning
When an air conditioning unit is fitted, the mechanical
operation of the heater controls remains unaltered.
However the air conditioning evaporator is positioned
in front of the mixing chamber through which all air
flow passes.
